Definitions
- Eurobaiisen are punctual data transmission devices in the track, which transfer data like a transponder when crossing a rail vehicle.
- the transmitted data are recorded when crossing the Eurobalise by a EurobalisenEnglishinraum device and transmitted to Switzerlandbeeinhneung on.
- the electromagnetic interference can be caused in particular by radio transmitters, which are located locally relatively close to the track and transmit in the uplink frequency range of Eurobaiisen, ie in the frequency range in which the Eurobaiisen send their payload information.
- radio transmitters which are located locally relatively close to the track and transmit in the uplink frequency range of Eurobaiisen, ie in the frequency range in which the Eurobaiisen send their payload information.
- the uplink range the range of 2.5 MHz to 6.0 MHz can be considered.
- the Eurobalisentech does not need to comply with the usual electromagnetic immunity.
- non-system radio transmitters in the Eurobalise Uplink frequency range transmit very narrowband and can, from the vehicle's point of view, look like constant "0" or "1" transmitting balises and thus lead to an operational disturbance.
- a threshold has been introduced which in many cases suppresses interfering radio transmitters; these radio transmitters thus have no influence on the EurobalisenHerinraum.
- Such a threshold is prescribed for protection against crosstalk.
- this known method fails when a disturbing radio transmitter exceeds this threshold. This may be the case for radio transmitters with high transmission power, which may also be close to the track.
- Another measure against disturbing influence of the Eurobalisenschreibintechnik by interfering radio transmitter is that the received signal is time filtered. The signals from Eurobaiisen are always received over a certain minimum distance; Based on the vehicle speed, this results in a minimum receiving time. All received signals shorter than this minimum receiving time are regarded as a fault by the Eurobalise vehicle equipment and are ignored. However, this method will fail if the jammer is received for longer than this minimum receive time, which is very often the case.
- the invention is based on the object to propose a Eurobalisen- vehicle device with which interference with radio transmitters are avoided with great certainty.
- a EurobalisenGermaninraum is equipped with two receiving loop antennas with the same reception characteristics and the same spatial orientation and with an attached to the receiving loop antennas evaluation that features a eurobalis foreign reception when passing a transmitter when the reception level difference of the receiving Frame antenna has been located during the presence of a reference signal predominantly below a predetermined lower receive level, wherein the reference signal corresponds to a detectable upon passing the transmitter receive signal.
- Each receiving loop antenna preferably consists of a single turn and is therefore often referred to in technical jargon as "loop".
- US Pat. No. 6,693,562 B2 discloses a Eurobalisen vehicle device having two receiving loop antennas and an evaluation device connected thereto, in this case the received signals of the frame receiving antennas are evaluated in the evaluation device in this way. ensures that a position of the vehicle can be reached just above the eu- robalise in the track.
- the invention is based on the finding that a Eurobalise is characterized by an inhomogeneous transmission field, as shown in FIG.
- the transmission field of a - interfering - radio transmitter is generally much more homogeneous, as shown in Figure 2. This difference can be exploited to differentiate Eurobaiisen and interfering radio transmitters with relatively homogeneous transmission fields.
- the two receive-frame antennas are provided with the same reception properties and the same spatial orientation and are used to compare the field strength and the phase of each received magnetic field at the locations of the two receive-frame antennas. In a homogeneous or predominantly homogeneous field, field strength and phase are the same or very similar in both receive loop antennas.
- the receive loop antennas detect different field strengths and phases. By means of a difference formation of the received signals of the two receiving loop antennas, it is then easy to determine a homogeneity of the electric field which is possibly caused by a transmitter foreign to the vehicle.
- the reception level difference of the receive frame antennas is almost zero, which is used according to the invention to identify a non-eurobaloid signal when passing the transmitter, if the receive level difference of the receive frame antennas during the presence of the reference signal or received signal from Sender has mainly located below a predetermined lower receive level (Sw). A faulty train control by a jammer is thus avoidable.
- the European Union robotic vehicle device can be designed in different ways. It is regarded as particularly advantageous if the two receiving loop antennas are assigned an additional receiving antenna whose received signal karssignal forms, and the evaluation has an additional input for the additional receiving loop antenna.
- the evaluation of the received signals supplied by the two receiving loop antennas and their connection to the evaluation device can be carried out in different ways.
- the two receiving frame antennas are connected to a differential imager in the evaluation device, which forms an electrical signal corresponding to the reception level difference; to the difference formers, a comparator is connected, which emits in the presence of the received signal and at a predominantly below the predetermined lower receive level lying receive level difference of the receive loop antennas a eurobalis foreign reception characterizing signals at the output of Eurobalisenment.
- a level comparator unit which, when the received signal is present and at a reception level difference of the receive frame antennas lying below the predefined lower reception level, identifies a reception which is not related to eurobalis. drawing signals at the output of the EurobalisenINDinrich- device.
- the advantage of this embodiment of the EurobalisenGermaninraum invention is that it manages without a special difference generator, because by the circuit coupling of the two receiving loop antennas at the common output of the series connection of these two loop antennas a receiving level difference is pending. Furthermore, it is considered advantageous to connect the two receiving frame antennas with a summation generator in the evaluation device, which determines a receive level -Sum of the receive frame antennas as received signal of the transmitter; the receiving loop antennas are connected to a difference imager in the evaluation device, which forms an electrical signal corresponding to the received level difference, and to the difference generator a comparator is connected, which is present in the presence of the received signal and below the predetermined lower reception level lying receiving level difference of the receive loop antennas emits a non-eurobaliser receiving signals at the output of EurobalisenGermaninraum.
- the invention further relates to a method for operating a EurobalisenGermaninraum and has set itself the task of such a method in such a way that with interference by interference signals disturbing influence of EurobalisenGermaninraum is avoided.
- the invention provides a method for operating a EurobalisenGermaninutter with two receiving loop antennas loop antennas with the same reception characteristics and the same spatial orientation and with a connected to the receiving loop antennas Auswer- te founded in which is passed when passing a transmitter from a eurobalis foreign reception when the receive level difference of the receive frame antennas during the presence of a reference signal predominantly below a predetermined lower receiving level (Sw) has been located, wherein the reference signal corresponds to a detectable when passing the transmitter receive signal.
- Sw predetermined lower receiving level
- the inventive method is particularly advantageous when the received signal of an additional receiving antenna is used as the reference signal, which is assigned to the two receiving frame antennas, and as the evaluation means an evaluation device is used with an additional input for the additional receiving loop antenna.
- a differential imager- a difference of the receiving level difference of the two receiving loop antennas electrical signal is formed, and by means of a comparator connected to the difference in the presence of the reference signal and at a predominantly below the predetermined At the lower reception level of the receiving frame antennas, a signal indicative of a non-eurobalisoid signal is output at the output of the EurobalisenINDinrich- device.
- a signal indicative of a non-eurobalisoid signal is output at the output of the EurobalisenEnglishrich- device.
- Another embodiment of the method according to the invention can be used with the same advantageous result, in which two receiving frame antennas connected in a crosswise manner are used such that the receiving level difference of the two receiving frame antennas is present at the common output of the series connection, and by means of one the common output of the series connection in the evaluation connected level - comparator unit in the presence of the received signal and at a lying below the predetermined lower receive level receive level difference of the receive loop antennas a eurobalis foreign reception characterizing signals are output at the output of the evaluation.
- a summation generator connected to the two receiving frame antennas in the evaluation device, to determine a receive level sum of the receive frame antennas as a receive signal and by means of a subtractor connected to the receive frame antennas to form in the evaluation device an electrical signal corresponding to the reception level difference;
- a comparator connected to the difference generator, when the reception signal is present and at a reception level difference of the reception frame antennas which is below the predetermined lower reception level, signals indicative of a non-eurobal sense reception are generated at the output of the Eurobalisen vehicle device.
- FIG. 3 shows an embodiment of a Eurobalisen vehicle device according to the invention with two receiving frame antennas and an additional receive loop antenna, in FIG
- FIG. 4 is a diagram showing the history of the reception level difference of the two reception loop antennas in a Eurobaiise crossing, in FIG.
- the illustrated eurobalis vehicle device 1 has a first receiving loop antenna 2 and a further receiving loop antenna 3, each consisting of one turn.
- the two receiving loop antennas 2 and 3 are the same design, ie they have the same reception properties and have the same spatial orientation, are therefore sized equal and juxtaposed on a surface F, the size of the surface of a transmission loop antenna, not shown also not shown corresponding Eurobalise corresponds.
- an additional receive-frame antenna 4 is arranged on the surface F, which encompasses the two receive-frame antennas 2 and 3.
- the receiving loop antenna 2 is connected via terminals 5 and 6 to a difference former 7 in an evaluation device 8.
- the further receiving frame antenna 3 is connected to the difference former 7 with further terminals 9 and 10.
- an electrical signal Sd is thus generated at its outputs 11 and 12, which corresponds to a reception level difference of the two receiving frame antennas 2 and 3.
- the additional receiving loop antenna 4 is also connected to the evaluation device 8 with its outputs 13 and 14 and supplies a reference signal which, when a transmitter passes, corresponds to the received signal originating from it.
- a reference signal which, when a transmitter passes, corresponds to the received signal originating from it.
- a curve K1 shows the absolute value of the received signal at the outputs 13 and 14 of the additional ones Reception loop antenna 4 on.
- the curve K2 shows how the absolute amount of the reception level difference of the two reception loop antennas 2 and 3 and the electric signal Sd changes at the Eurobaiise crossing. At the point indicated by "0" or the center of the Eurobalise, not shown, the reception level difference or the electrical signal Sd assumes a value of 0.
- FIG. 5 shows how the ratios with respect to the received-level difference look when an arbitrary transmitter is crossed over instead of a Eurobalise.
- a curve K3 indicates the absolute value of the sound level P received at the additional receiver-frame antenna 4 of the transmitter called by the transmitter Receive or reference signal again, while the curve K4 or the horizontal straight line indicates that the reception level difference is very low.
- the value of the curve K4 is always below the threshold value Sw in the presence of the received signal, which is evaluated in such a way that the received signals originate from an interference source.
- a signal indicative of a non-eurobalis receipt occurs; a disturbance by, for example, a radio transmitter as transmitter remains without influence on the train control.
- the Eurobalise vehicle device 16 according to FIG. 6 is comparatively simple in construction because it has only once again a first receiving-frame antenna 18 and a second receiving-frame antenna 19.
- the two loop antennas 18 and 19 are with their terminals 20 and 21 and 22 and 23 each for themselves with a difference former 24 and a Summarizer 25 connected in an evaluation device 26.
- a difference signal Sd which corresponds to the reception level difference of the two reception frame antennas 18 and 19
- a sum signal Ss is present at the outputs 29 and 30 of the summation generator 25 occurs, which represents the sum of the reception levels of the reception loop antennas 18 and 19.
- This sum signal Ss corresponds to a received signal of a transmitter, thus represents the signal of the Eurobalise in undisturbed operation when driving over a Eurobalise and therefore stands in undisturbed operation at an output 31 of the evaluation device 26 or the Eurobalisen vehicle device 16 as a euro-balise signal because the difference signal Sd is predominantly above the predetermined threshold Sw.
- a signal indicative of a non-eurobalisoid signal is output by the evaluation device 47 at its output 48, and no train influence takes place, because in this case the received signals are caused by an interfering radio transmitter.
